MAGNET STRENGTH Name:________________________________________ Date__________________________________________
Problem: Do all magnets have the same strength? Hypothesis: I think if_____________________________________ __________________________________________________________ _________________________________________________________. Materials: Five to ten different kinds of magnets (bar, large U, small U, horseshoes, rectangles, cylinder, round, with holes, etc), paper clips. Procedure: For each magnet, place one paper clip at a time. Keep on building a chain until the magnet will no longer hold any paper clips. Record the number of paper clips each magnet held. Observations: Create a graph by logging on to http://nces.ed.gov/nceskids/Graphing and entering the correct information. Choose the type of graph you would like to create. Save the graph by following the directions on the screen. Print the graph. Paste the completed graph here:
Conclusion: List at least three things you learned about magnet strength. __________________________________________________________ __________________________________________________________ __________________________________________________________ __________________________________________________________ __________________________________________________________ |
